Quad Channel DVI-I Capture Card

Capture four DVI-I High Definition DVI streams in a single capture card.

The Xtreme-HD4 is an eight lane PCI Express capture card with four independent video capture channels, supporting HD capture.

This video capture card provides a high performance high density video capture solution for control room, medical and other applications that require high capture bandwidth. The quad HD capture capability in combination with EMS’s multi stream and synchronization features enables resolutions up to 4096×2048 and Quad HD solutions.


The Xtreme-HD4 captures all four HD video channels simultaneously and triple buffers them into onboard storage for tear free video, alongside embedded HDMI audio streams can also be captured from each channel.

This full length video capture card has four capture processors, each providing 800 MB/s bandwidth.

Quad DVI‐I Capture Channel:

• HDMI / DVI / RGB /YPbPrVideo Capture
• Maximum resolution up to 4096 x 2048, at 165 MHz Pixel Clock (Digital modes) or 170 Msps in analogue modes.
• HDMI audio capture with streaming from each DVI Channel
• ~800 MB/s bandwidth per capture processor, 3.2GB/s for the card

Video Streaming Support

DirectShow drivers for WDM Streaming driver supports the following applications, to encode, record and stream video over networks or the Internet:
• Microsoft Media Encoder®
• VirtualDub
• Any other DirectShow encoding software

For streaming applications, the Xtreme‐HD4 can be used with Windows Media Encoder to compress and stream captured video. To replay the video, use Windows® Media Player.

Any application compatible with Windows® DirectShow technology can use the Xtreme‐HD4 due to it built‐in WDM support.

Audio Features

HDMIAudio capture and streaming from each DVI Channel supports audio capture to the PCI Express bus at popular sample rates from 44.1 to 96 ksamples/s at 16 bits/sample. The card supports playback and mixing of HDMI embedded audio.

EMS Software

The Xtreme‐HD4 is supplied with a powerful software application for configuring the format of the input sources and displaying the data. Simply connect your video source into the card, run the Xtreme‐HD4 application to automatically detect the video source format and display the captured video in a window on your desktop.
